1. What did French lawmakers propose for stablecoin swaps?
French lawmakers have put forward a plan to extend the country's 31.4% crypto capital gains tax to swaps into euro-regulated stablecoins, and Francois Volpoet, France chief executive at blockchain analytics firm Chainalysis, warned on October 14 that the idea could push traders toward offshore channels that authorities cannot see. The change would take effect on January 1, 2027, if it survives the budget process.
The measure is one piece of the 2027 budget bill. The National Assembly began debating the budget in the week before this report and has until December 10 to pass it. Nothing described here is law yet, and several of the crypto provisions still have to be argued again before the full chamber.
2. How would the stablecoin swap tax work?
The National Assembly's finance committee adopted an amendment on October 7 that would turn a particular kind of trade into a taxable event: exchanging a cryptocurrency such as bitcoin (BTC) for a stablecoin classified as an electronic money token under the European Union's Markets in Crypto-Assets rulebook, known as MiCA. That framework took full effect on July 1.
Under present French practice, swapping one crypto asset for another is generally not taxed. Tax is due when holders cash out into traditional currency or spend crypto on goods and services, at a flat rate of 31.4%. The amendment would add a new trigger, applying from January 1, 2027, whenever a trader moves into one of the regulated stablecoins.
The scope matters. Because the proposal reaches only stablecoins that fall under MiCA's electronic money token category, tokens issued outside that regime would not face the same treatment. That gap sits at the center of the objections raised by industry voices.
3. Why could the tax drive traders offshore?
Chainalysis argues that the design creates an incentive to choose less transparent products. If swapping into a regulated, euro-area stablecoin triggers a tax bill while swapping into an unregulated alternative does not, some investors may prefer the latter, moving activity away from instruments that come with issuer obligations and oversight.
Volpoet said the measure could weaken efforts to draw crypto transactions into the regulated financial system. He framed the trade-off in a quote sent by email: "Do we want more taxpayers to declare their assets, or a higher tax rate applied to a base that is increasingly evaded?"
He added that authorities find it easier to monitor transfers of regulated stablecoins than activity in decentralized finance or in self-hosted wallets. In his reading, steering users away from regulated tokens would shrink the portion of the market that tax and compliance teams can observe.
4. What is the self-hosted wallet declaration rule?
A second finance committee amendment, backed on October 9, would oblige French taxpayers to declare self-hosted wallets holding at least €100,000, roughly $116,000. A self-hosted wallet is one in which the user, not an exchange or custodian, holds the private keys. Failing to comply would carry fines of up to about $11,600.
Volpoet questioned whether such disclosures could be kept safe, pointing to a rise in physical attacks on crypto holders in France. Data from blockchain security firm CertiK shows Europe recorded 39 of 52 such incidents worldwide as of July, with France alone accounting for 33, or 63.5% of the global total. His concern is that a register of large holders could become a target list if it leaked.
The wallet declaration rule would place a list of substantial self-custody holders in the hands of the tax authorities. Volpoet's worry is not about the tax office itself but about what happens if such data were ever exposed or misused. In a country where, per the CertiK figures he cited, 33 of the 52 physical attacks on crypto holders recorded worldwide as of July took place, any record that identifies people with large holdings is a sensitive asset.
The €100,000 threshold limits the rule to larger holders, but those are also the individuals most likely to be targeted by criminals who know that crypto can be seized by force. Policymakers face the task of balancing transparency for tax purposes against the personal safety of the people who would be required to disclose, and they will have to explain how such records would be protected before the obligation takes effect.
5. What other crypto tax changes are on the table?
Lawmakers also backed extending France's exit tax to crypto holdings worth roughly $900,000 or more. The exit tax applies rules already used for wealthy shareholders who relocate abroad, bringing unrealized gains into the tax base at the moment of departure.
A third amendment, supported on October 7, would let investors carry crypto losses forward for up to 10 years. That would bring the treatment of digital assets closer to that of stocks, and it softens a package that otherwise leans toward stricter reporting and broader taxation.
6. How does the French plan compare with Greece and the rest of Europe?
Other European governments are choosing different paths. Greece published a draft bill for public consultation in the week before this report that would set a 10% capital gains tax on crypto. By contrast, Germany, France and Italy have set or plan rates above 25%.
The spread shows how unsettled European crypto taxation remains even after MiCA harmonized licensing and consumer-protection rules. Tax remains a national matter, so traders can compare regimes, which is part of why industry analysts watch whether higher rates or new triggers encourage relocation or the use of unmonitored venues.
7. Why does the difference between regulated and unregulated stablecoins matter?
A stablecoin is a token designed to hold a steady value, usually by tracking a national currency. Traders rely on them as a parking place between positions, because moving into a stablecoin lets them step out of volatile assets without withdrawing to a bank account. That everyday role is why a tax on the move itself would be felt far more widely than a tax on cashing out.
MiCA sorts tokens into categories, and the electronic money token is the one meant for stablecoins pegged to a single official currency. Issuers of these tokens must be authorized, hold reserves and meet disclosure requirements. Tokens that do not fit the category are not covered in the same way, and some are issued from jurisdictions outside the European Union. A tax that applies only to the first group effectively penalizes the products that regulators in Brussels have been trying to encourage.
Chainalysis frames the issue as one of visibility. Regulated issuers can be asked for data, exchanges that list them have reporting duties, and blockchain analytics can trace flows between known entities. The more activity migrates to tokens and venues outside that perimeter, the harder it becomes for tax administrations to match transactions with taxpayers.
8. What is a taxable event, and why would a new one change behavior?
In tax terms, a taxable event is any action that creates a liability: selling an asset for a profit, spending it, or, under the proposal, exchanging it for a particular category of token. France has so far taxed crypto when it leaves the crypto ecosystem, which let holders rebalance between assets without paperwork. Adding a trigger for swaps into regulated stablecoins would require records of each such exchange, including the value of the asset given up at the time of the trade.
Behavioral effects follow from that extra burden. Holders could swap less often, delay conversions, route trades through alternative tokens or move to platforms based abroad. Supporters of the proposal presumably see the swap as a realization of gains that deserves to be taxed; critics, including Chainalysis, argue that the revenue is likely to be smaller than expected if the base moves out of sight.
9. What would the exit tax and loss carryforward mean for investors?
The exit tax proposal targets people with large unrealized gains who plan to leave France. Under the rules already used for wealthy shareholders, moving abroad can bring latent gains into the tax base at the time of departure, instead of letting them escape French tax by changing residence. Extending that logic to crypto holdings worth roughly $900,000 or more would close what lawmakers evidently see as a loophole for the most successful holders.
The ten-year loss carryforward points the other way. Today, a trader who loses money in one period has limited ways to offset it against later profits. Allowing losses to be carried forward for up to a decade would let investors reduce future liabilities, aligning digital assets more closely with how stocks are handled. For long-term holders who endured deep drawdowns, the provision could be worth more than the new swap tax costs them, though that depends on the final text.
Taken together, the amendments describe a tax regime that is moving toward more reporting and broader reach while offering some relief on losses. Investors and platforms serving French customers will be watching which parts survive the full Assembly debate, since compliance systems would need to be built before January 2027 if the swap tax proceeds.
10. What happens next for the French budget?
The finance committee rejected the budget's revenue section by a vote of 31 to 3, which means the crypto amendments will have to be debated again by the full National Assembly. The vote on the revenue portion is scheduled for October 20, and lawmakers have until December 10 to complete passage of the 2027 budget.
Until then, the stablecoin swap tax, the €100,000 wallet declaration, the extended exit tax and the 10-year loss carryforward all remain proposals. Any of them could be altered, dropped or strengthened before the final text is adopted.
